I recently switched from directly being plugged into my modem, to a
router-system at home for my computer.

However, the problem is that I get the "Unidentified Network" in the
Networks section, and I can't ping my own IP or Default gate way, as it gives
me a "PING: transmit failed, error code 1231." message.

Currently, all my settings in the IPv4 protocol are set to auto, and setting
them manually makes no difference, except that it gives me error 1232 instead
of 1231...

It's probably also worth mentioning that Vista does connect to the network,
calling it the 'Network #', and during that second or two, I can get all the
numbers in ipconfig, but very soon after, Vista changes the 'Network #' to
'Unidentified Network', and all the numbers in ipconfig are lost. Vista also
states the my IP is used on the Network by another computer, even though it
definitely isn't.

I'm currently using Realtek RTL8168/8110 Family PCI Gigabit Ethernet NIC
running Vista Ultimate.
I have 4 other computers at home, all capable of connecting to the network,
and going on the internet and everything. (all running XP)

Vista obviously cannot repair the problem itself.
Any help would be greately appreciated.

1. Click Start, type ncpa.cpl in the Start Search box, and then
click ncpa.cpl in the Programs list.

If you are prompted for an administrator password or confirmation,
type the password, or click Continue.
2. Right-click the Gigabit network connection, and then click
Properties.

If you are prompted for an administrator password or confirmation,
type the password, or click Continue.
3. On the Networking tab, click Configure.
4. On the Advanced tab, click the property that is in the Property
box.
5. In the Value box, click the value that represents the 100 Mbps
Full Duplex setting, and then click OK.

okay done.. nothing really happened.. the network connection disabled itself,
then enabled itself again and is still "Unidentified Network", same situation.

what router are you using? brand/model/hardware rev? what firmware?
have you tried a factory reset of the router?

if the stack itself has become corrupt in Vista, try a reset by
opening an elevated cmd prompt (run as administrator) and typing

netsh int ip reset [enter]

then, please post the complete results of ipconfig /all from that
computer.

I'm using a Xincom Twin Wan Router XC-DPG502 Ver 2.1 Rel 2O.
I'm not doing a factory reset because I need to keep a lot of my settings on
the router.
I tried the reset, no difference. Btw: It's still set on full 100mbs duplex.
